He is talking about standard economic theory. Economic theory doesn't match any popular political platform - sometimes it agrees with Republicans and sometimes with Democrats and frequently with neither.

Granted, a lot of what Bush does is so stupid that it is hard not to get upset. And economic theory is unequivocably against his actions, hence the stream of anti-Bush articles. That adds an emotional emphasis.

But the emotional emphasis is not his point.
